Scalar Docs platform, Scalar
API reference and docs platform whose published sites always serve /llms.txt and /llms-full.txt, with links pointing at .md pages and OpenAPI files.
Work left to the developer: Low on hosted Scalar Docs; medium for self-hosted API references, which need their own llms.txt route.

Test build
Not test-built: the scores above come from the documentation pages cited in each row, read 4 November 2026, because the platform needs an account or a paid plan. The reason is in each evidence cell.
